                     Master thesis project: Carbon nanotubes as a material for cell-electrode interfacingDevelopment of new materials for in vitro and in vivo electrical recordings is a challenging task required for a successful brain-computer integration. One of the problems that should be solved is an increase of signal-to-noise ratio, which is especially difficult due to a relatively low magnitude of a neuronal action potential. Introduction of an artificial channels made of a small segments of carbon nanotubes into a cell membrane showed promising results with a perspective of acquiring non-invasive intracellular signals from cells.
Current project aims to further investigate a carbon nanotubes-cell interactions and develop a carbon nanotube-based functional coating for electrical recording devices. The methods used for that include:

• chemical preparation of small segments of carbon nanotubes from bulk amounts of material
• incorporation of nanotube segments in a model membrane
• evaluation of ion flow through the nanotube segment
• modification of nanotube segments with fluorescent dyes for tracking cell-nanotube interactions
• confocal microscopy of cells cultured on a nanotube-modified model membrane

                     Master thesis project: Development of stretchable and transparent holey electrodes on polymer substratesAt the Institute of Bioelectronics (ICS-8) at the Forschungszentrum Jülich, physicists, chemists, biologists, and engineers perform joint research on the scientific principles of the functional link between biological components and electronic components. This collaboration has led to the development of platforms for microfluidics, micro- and nano-patterning, and electronic biosensors. These technologies are not only developed to understand biological processes, but also pave the way for their application in sensor technology and diagnostics. With the advertised position we are planning to strengthen our research efforts to understand the biophysics of neuronal information processing.
Job Description:
With the aim to characterize neuronal networks, to diagnose, and to treat medical diseases, one of the research fields in our institute is the development of penetrating neural implants for in vivo applications targeting the brain and the retina. However, different physical and biological challenges have to be addressed before the intended application becomes feasible. One important issue to overcome is the mechanical mismatch between the tissue and the neural probes, as current standard materials used to fabricate such probes are mostly rigid and boost immune responses that cause the failure of the implant. Hence, thin layers of flexible and soft polymers such as polyimide, parylene-C, and silicon rubber are being implemented in the fabrication of such implants, making them more akin to the nervous tissue. Despite the flexibility, softness, and transparency gained when using polymers, the conductive layer of the electrode array still remains rigid and opaque, resulting in crack formations and limiting its use with different optical modalities. Therefore, with the purpose to have a full compliant neural implant, a strategy using stretchable holey electrodes on polymer substrates is proposed. In this project, the student is expected to establish the fabrication steps of the holey electrodes on different polymer substrates, applying techniques such as colloidal lithography and photolithography. Likewise, the project comprises optical and mechanical characterization methods like UV-VIS spectrophotometry, bending, and tension/compression tests, as well as the direct comparison of the holey structures with other stretchable geometries, such as the serpentine structures.
Your Profile:

• Student of material science, engineering, microsystems technologies or similar
• Bachelor student with similar experience are welcomed to apply
• Cleanroom experience
• Ability to communicate with scientists and technicians from various disciplines
• Well-structured and systematic research approach
• Independency
• Passion for science

• Fantastic research equipment facilities;
• Forschungszentrum Jülich located close to the interface between Belgium, the Netherlands and Germany and with strong links to the ABCD Region (Aachen, Bonn, Cologne, Düsseldorf) which is one of the leading high-tech regions in Europe.

Master thesis: Techno-economic Optimization Potential of Solar to Hydrogen Pathways

Framework:
In order to achieve the climate change targets of the German Government, power generation from domestic renewable energy sources (RES) must be increased significantly. Moreover, the import of renewable energy from countries with beneficial climatic conditions for harvesting solar or wind energy is discussed, at present. For the long-distance transport and long-term storage of electricity, hydrogen offers a feasible solution. In this context, system components of hydrogen production from renewable energies are being developed and systems analytical work is being carried out at Helmholtz Zentrum Berlin (HZB), Forschungszentrum Jülich (FZJ) and German Aerospace Center (DLR).

Hydrogen production utilizing solar radiation can be accomplished via different technologies. In previous studies, solar power generation by photovoltaic or solar‑thermal power plants and subsequent hydrogen production via high and low temperature electrolysis were considered. However, the direct comparison of these pathways is not fully consistent since these solar harvesting technologies are primarily optimized for electricity generation. The implementation of storage technologies, for example, could further reduce the hydrogen production costs for single technology pathways. The goal of this study is to investigate the greenhouse gas emissions reduction potential of different solar‑to‑hydrogen pathways and to perform a technical and economical assessment comparing these alternatives.

Your task:

    Literature review of solar hydrogen production and related technologies
    Incorporating collected data into existing models and databases at FZJ-IEK-3
    Design of a Python-based model on relevant solar hydrogen pathways focusing on the greenhouse gas emissions reduction potential
    Detailed analysis and comparison of results for each solar hydrogen pathway investigated

Your profile:

    Very good academic records in energy engineering, process engineering, mechanical engineering, industrial engineering or similar field
    Interest in power systems, future energy markets
    High individual motivation
    Good programming and analytical skills
    Experience in GIS and SQL databases desirable

Our offer:
We offer a pleasant working environment in a highly competent, international team within the Helmholtz Association, which is one of the most prestigious research organizations in Europe. The work will be supported by top-end scientific and technical infrastructure as well as close guidance from experts. You will have the opportunity to work with experienced researchers from various scientific fields and be part of designing the future European energy system. The work will be carried out at FZJ in Juelich and jointly supervised by experts from HZB (photovoltaic based concepts), FZJ (model-based systems analysis) and DLR (solar thermal processes). It would, however, be beneficial to conduct a part of the work at HZB in Berlin.
